As first noticed in [1]}, [2]}, the key to overcome this problem is to treat General Relativity as a low-energy effective field theory of an unknown ultraviolet (UV) theory of Quantum Gravity, with the Plank mass \(M_p=\frac{1}{\kappa }\sim 1.2 \times 10^{19} \ Gev\)  as the UV cutoff of this theory, that is the energy above which the EFT loses its validity. In order to consistently build an effective action describing this problem from a bottom-up approach we need to:
